Answer 1

Olá!

A)

$\frac{6}{9} + \frac{1}{3} \\ \frac{2}{3} + \frac{1}{3} \\ \frac{2 + 1}{3} \\ \frac{3}{3} = 1$

B)

$\frac{2}{5} + \frac{1}{6} \\ \frac{12 + 5}{30} \\ \frac{17}{30}$

C)

$\frac{5}{6} - \frac{10}{12} \\ \frac{5}{6} - \frac{5}{6} = 0$

D)

$\frac{1}{2} + \frac{1}{3} + \frac{1}{4} \\ \frac{6 + 4 + 3}{12} \\ \frac{13}{12}$

E)

$\frac{3}{15} + \frac{1}{5} - \frac{2}{10} \\ \frac{1}{5} + \frac{1}{5} - \frac{1}{5} \\ 0 + \frac{1}{5} = \frac{1}{5}$

Espero ter ajudado :)
